Abstract
A method includes a first bonding step including providing a first polarizing film obtained by transversely cutting a first long polarizing film having an absorption axis in its longitudinal direction, supplying the first polarizing film from a first optical film roll, and bonding the first polarizing film to a back side of the optical cell while feeding the optical cell; and a second bonding step including providing a linearly polarized light separating film obtained by transversely cutting a long linearly polarized light separating film having a reflection axis in its transverse direction, supplying the linearly polarized light separating film from a second optical film roll, and bonding the linearly polarized light separating film onto the first polarizing film bonded to the back side of the optical cell, while feeding the optical cell.
